Abstract
Description
- This invention relates to motorized conveyor rollers and particularly relates to a motorized conveyor roller having a rotatable portion disposed between two opposite stationary ends. The invention also relates to the method of barring access to a motorized rotatable conveyor roller for driving a conveyor medium by disposing the motorized rotatable conveyor rollers between opposed generally cylindrical stationary ends.
- A variety of conveyor roller systems have heretofore been designed and utilized. A large variety of known conveyor roller systems comprise a continuous belt or conveyor medium which travels over a series of rollers. The rollers can be simple shafts on which may be mounted various forms of sprockets or drive means for supporting the conveyor medium. Some advanced conveyor systems utilize enclosed and sealed drive rollers with the drive motors contained inside the rollers themselves.
- An example of such motorized conveyor roller is disclosed in U.S. Pat. No. 5,088,596 which teaches a motorized conveyor roller mounted in a conveyer frame to support and propel articles from one end of the conveyor path towards the opposite end. The conveyer roller includes a roller tube rotatably mounted in the conveyor frame and drive means contained inside the roller tube for driving the roller tube. The drive means includes a motor, a gear reducer assembly operatively connected to the motor, and a drive member connected to the outward shaft of the speed reducer for engaging and rotating the roller tube.
- Furthermore there has been a concern by some to improve the safety features of conveyor rollers and particularly motorized conveyor rollers. For example, U.S. Pat. No. 5,642,799 illustrates a brake device for a conveyor having two load supporting conveyor rollers rotatable to engage a load thereon to be transported along the conveyor. The load supporting rollers are movably transversely to their axis of rotation by a load passing there over against a resilient bias into engagement with a brake roller adapted to brake rotation of the conveyor rollers.
- Moreover U.S. Pat. No. 5,143,184 illustrates a safety shutdown system for luggage conveyor systems.
- Furthermore U.S. Pat. No. 6,082,528 teaches a conveyor roller.
- There is, however, a need to improve the safety features of motorized conveyor rollers.
- It is a further object of this invention to provide an improved motorized conveyor roller and method thereof.
- It is an aspect of this invention to provide a motorized conveyor roller having a rotatable portion and at least one stationary end.
- It is a further aspect of this invention to provide a motorized conveyor roller for supporting and driving a conveyor medium comprising a hollow drum defining a rotatable supporting surface having a cylindrical shape disposed between said first and second generally cylindrical stationary ends; said first and second generally cylindrical stationary ends co-axially mounted to first and second spaced apart stationary shafts respectively; one end of each of said stationary shafts disposed internally of said hollow drum for carrying drive means for rotating said hollow drum between said generally cylindrical stationary ends.
- It is yet a further aspect of this invention to provide a method of barring access to a motorized rotatable conveyor roller for driving a conveyor medium by disposing said motorized rotatable conveyor roller between opposed generally cylindrical stationary ends.
- These and other objects and features of the invention shall now be described in relation to the following drawings.
-
FIG. 1 is a full cross-sectional view of a motorized conveyor roller. -
FIG. 2 is an end view ofFIG. 1 . - In the description, which follows, like parts are marked throughout the specification and the drawings with the same respective reference numerals.

outer surface 95 ofhollow drum 1 presents an outer diameter D3 which is slightly greater than the diameter of each of the generally cylindrical stationary ends D1 and D2.

Furthermore theouter surface 95 can include any variety of means to increase the co-efficient of friction between theouter surface 95 and the conveyor medium such as for example by knurling or machining a spiral at each end toward the center or by covering theouter surface 95 with rubber. - Furthermore the

rotatable conveyor roller 1 which drives a conveyor medium by disposing the motorizedrotatable conveyor roller 1 between opposed generally cylindrical stationary ends 54 and 55. - Accordingly if someone near the conveyor system accidentally touches the end of the
motorized conveyor roller 60, they will come into contact with the stationary ends 54 and 55 thereby preventing any damage which may otherwise occur where a person would come in contact with rotating parts which may cause physical damage or catch any loose clothing drawing a person into the system. - Furthermore the invention described herein can be utilized to retrofit existing motorized conveyor rollers having one
end stationary shafts shafts - Moreover although the stationary ends 54 and 55 are shown as secured to the first and second
stationary shafts shafts - Typically there is a small gap between the ends of the first and second stationary ends 54 and 55 and
end flange 2A and endflange 2B. For example, such gap may be in the vicinity of 0.04 inch although such example should not be interpreted as limiting but only as an example. - The invention described herein illustrates a rotatable roller having cylindrical ends disengaged from the rotational movement of the rotational roller.
- Various embodiments of the invention have now been described in detail. Since changes in and/or additions to the above-described best mode may be made without departing from the nature, spirit or scope of the invention, the invention is not to be limited to said details.
